G. The word confidant reminds me of a movie i saw on the Hallmark channel called the Secret Keeper. She was a girl in town who would listen to kids secrets for a penny, a penny for your thoughts, and give them advice while promising to keep their secret. She was the trustworthy confident many kids sought after.
